This would make it very quick to tells a tickets status without having to read the text. Especially when you have a long list of tickets or just want to quickly skim search results.
Example:
- Closed - Red
- Open - Green
- Pending - Orange
Ideally per-user configurable so people can pick their own colour scheme. I can also see it being useful in some scenarios to have a global override (configured by an admin) so say a closed ticket always displays red.
